[bug#54866] [PATCH] docker-compose, python-pyyaml

Hi Guix,

I noticed that after my last pull to 6413d0898b92, docker-compose did
not build anymore. The backtrace showed that it fails in the sanity-
check-phase due to the requirement python-pyyaml <6.

As it builds nicely on guix 9bd4ed3, which still features
python-pyyaml@5.4.1 I took the definition from there, re-added it to
python-xyz.scm and adjusted docker-compose in docker.scm.  You find the
patchfile attached, as evolution seems to mess with line-breaks
(docker-compose build tested on x86_64 only, as I don't have anything
else around).

Best & thanks for your great work,
Daniel
